I found this interesting reference, its from MGA’s secretary, Mufti Muhammad Sadiq.
“””Pir Sirajul Haq killed many dogs in Qadiyan with poison. Lads on the street would tease him with the nick-name of “kuttay maar” (dog-killer). When he complained to the Promised Messiah, he said, “What is wrong with that? In the hadith my name is “Sooar Maar” (swine-killer); it is written that the Messiah will kill swine”””” (Zikr-e-Habeeb by Mufti Muhammad Sadiq Qadiyani p.162.)
